Harry gave me some of the soon to be available Predator motors to experiment with......
So I thought I would build a "House Car" for the Summer Slam to see if the milder motor could be made to be
competitive with the Piranhas.......
I built a lightweight chassis using the usual 3/64 & even some 1/32 brass rod..
I made a concession to a motor mount with oilite bearings & WRP guide mount...( I coulda' made it lighter without these)
I used 3/8" Pro-Track wheels instead of the usual 1/2"
This meant trimming about 1/16 off the Paul Gage rears & about 1/8 off the fronts.
I used a modified & lightened '38 Chevy coupe casting...
I fudged around with gears using a 10:26 final ratio.....
I wound up with an 88 gram finished car.
On my track it runs VERY smooth & nimble also seems to be pretty quick.....we'll see how it runs on the bigger HRW oval......
Just need to ship it to Harry.............
